Summary/Conclusion

This study demonstrates that incorporation of IORT as a component of multimodality management of patients with locally recurrent ESTS achieves high rates of local control and limb salvage with acceptable treatment morbidity and suggests that prior EBRT does not significantly influence disease control or toxicity. This technique offers a method of delivering focal therapy to achieve local control for the majority of patients who otherwise may require more radical surgical procedures.

2014 SICPRE Congress Best Abstracts – Aesthetic Evaluation in Oncoplastic and Conservative Breast Surgery: A Comparative Analysis

Treatment Use

Electron IORT

Cancer Indication

Breast (Single-Fraction APBI)

Number of Patients

107

Summary/Conclusion

Background In conservative breast surgery, the achievement of a satisfactory cosmetic result could be challenging; oncoplastic techniques may be helpful in many cases. A comparative analysis was performed among 3 groups of patients undergoing oncoplastic techniques plus external radiation therapy or intraoperative radiotherapy (IORT) and breast conservative surgery plus external radiation therapy; long-term oncologic results … Continued

Ultrahigh dose-rate FLASH irradiation increases the differential response between normal and tumor tissue in mice

Treatment Use

FLASH-RT

Cancer Indication

Electron-beam FLASH

Number of Patients

0

Summary/Conclusion

Pulsed irradiation (FLASH) was performed using the 4.5 MeV linear electron accelerator (LINAC) described in (34). The system allows exposure of cells or animals to a single submicrosecond pulse, to any sequence of pulses, or to split-dose irradiation with an interval between fractions ranging from fractions of seconds to a few minutes.
